SAFETY-PIN.

SPECIFICATION formingpart of Letters Patent No. 756,809, dated April 12,1904.

Application filed January 30, 1903. Serial No. 141,097. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN ANDREsEN, a

citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and usefulImprovements in Safety- Pins, of which the following is a specificationcontaining a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to safety-pins; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

In the drawings, Figure 1 is a side view of my invention with the shieldthereof in section. Fig. 2 is a similar view with the safetypin open.Fig. 3 is a detail enlarged view, with parts broken away, of the movablemember of my invention, showing the hole therethrough. Fig. 4 is asectional view taken on the line 1 t of Fig. 2. Fig. 5 is a sectionalView taken on the line 5 5 of Fig. 2. Fig. 6 is a side view, with partsbroken away, of a modified form of construction of my invention. Fig. 7is a sectional view taken on the line 7 7 of Fig. 6.

Referring to the drawings, 1 indicates the fixed member, 2 the movablemember, and 3 the usual spring-coil, which spring-coil is protected inthe usual manner by the sheet-metal clamp or clasp 4.. Mounted on thefixed member 1 is a sheet-metal shield 5. This sheetmetal shield 5 isprovided with the usual lateral stop-flange 6, and said shield 5 may besecured to the fixed member 1 in any suitable and mechanical manner.

The essential feature of my invention is providing the movable member 2with an eye, such as 7. This eye 7 is preferably elongated, as shown,extending longitudinally of the movable member 2. The movable member 2is also provided with a pointed portion 8.

The fixed member 1 has its free end terminating in a hook 9, which isadapted to be engaged into the eye 7 of the movable member 2. Thespecial construction of this hook 9 is shown in Figs. 1, 2, and 5,wherein it is shown that said hook is an integral portion formed on thefree end of the fixed member 1. This is preferably done by a suitabledie or instrument by pressing or molding the free end of the member 1into a hook of this character or any suitable form susceptible ofengagement into the movable member. It will also be noticed by referringto Figs. 1 and 2 that the free end of the fixed member 1 passes aroundthrough the shield 5, by which said shield is held from lateral movementon the member.

The metal shield 5 is provided with a contracted or flaring mouth oropening 10, which is approximately of the width of the natural thicknessof the movable member 2. This contracted opening or mouth 10 acts as aguideway for guiding the eye 7 of the movable member 2 onto and inengagement with the hook 9. It will be noticed, as heretoforestated,that I have designated the portion 9 as a hook, and I desire topoint out in this connection that said hook is especially constructedand acts as a lock or fixed resistance to the member 2 regardless ofwhatever strain may be applied to said hook through the member underoperative conditions. In other words, it will be noticed that said hook9 is provided with a recess 11. The wall of said recess is adapted toengage the inner surface of the eye 7, which lies adjacent the point 8of the movablemember 2-that is, under conditions when force or pull isapplied to the safety-pin when in use.

It will be understood by referring to Fig.1, wherein the movable member2 is shown looked, that whatever force or strain is applied 'to themember 2 the pointed portion 8 will occupy the position which itoccupies in said figure.

Referring to Figs. 6 and 7, which show modified forms of construction,it will be noticed that I form thehook 12 out of the metal composing theshield 5, which is done by being stamped directly from the materialcomposing the shield 5.

Although I have shown in connection with my invention the shield 5, itmay be noted in this connection that I can dispense with the shield 5 byusing the bent portion 13 of the fixed member 1 as a shield for thepoint of the movable member by pressing or forming said portion 13 insuch a manner as to make it answer the purpose of a guard or shield forthe point 8.

It will be noticed from the foregoing de scription that I have inventeda safety-pin which when in use is absolutely locked under any and allnormal conditions.

The hook 9 is formed of sheet metal and is stamped directly from theguard, and it is disposed longitudinally with the guard and centrallywith the restricted opening 10.

Having fully described my invention, what I claim is A safety-pin,comprising a fixed member, a
